Specification of Letters Patent..

Patented oct. 17, '1916.

Application led J une 22, 19116. Serial' N o. 105,273'.

To all whom t may concern:

Be it known that I, MrL'roN L. HALTEMAN, a citizen of the United States, residing inthe city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented an Improved Lock, of which the following is a specification.

My invention is an improved lock designed to provide simple, inexpensive, and efficient means for drawing together, 'securely holding and sealing separable parts, morerparticularly for securing the lids to-the bodies of boxes, trunks and the like, but it will be understoodthatit may be used in various relations. y f

The nature and characteristic features of my invention are fully disclosed in the following description and vthe accompanying drawings in illustration thereof. j

In the drawings, Figure 1 is a front `elevation of my improved lock applied to a container having parts thereof broken away; Fig. 2 is a front elevation showing a second position of the construction illustrated in Fig. 1; Fig. 3 is a sectional view showing the initial locking relation; Fig. 4 is a plan view of the detached base of the lock, and Fig. 5 is a plan view of the inner side of the detached cam disk.

vThe invention, as illustrated in the drawings, is applied to a structure, such as a box, comprising the body 1 and the lid or door 2. The lock comprises a base plate or disk 3 prov vided with a peripheral flange 4, a radial notch or recess 5, peripheral apertures 6, a

central aperture 7, and an eccentric countern sunk aperture 8, the latter being designed to receive a stud or screw 9 for engaging the base to the body 1 with the entrance of the notch 5 disposed adjacent to the edge of the part 1 on which the part 2 bears.

A cam and cap disk 10 has the flat peripheral part 11 which is adapted to engage the disk 3 in closely fitting relation within the flange 4, the body 12 offset from the part 11 to which itis joined by the cam 13, the radial way or throat 14 through the part 11 to the part 13, the aperture 15 adapted for registering with the aperture 7 (so that a bolt or rivet 16 can be passed therethroughto secure the part 11 in revoluble relation to the part 3 and the parts 3 and 11 in desired relation to the part 1), a socket 17 for a wrench 18 (adapted to fit over the head of the bolt or'rivet 16 so as to revolve thereon and turn the disk 10)., and the vperipheral notches or apertures 19 adapted to register with the aperturesG for the passage of a Wire 20', to

.be twisted for the. purpose of sealing the part 10 in its desired relation to the part `3. A hasp 21 is fixed to the lid 2 and is provided with a tongue 22 having a kprojection 23 thereon, the tonguey and projection being adapted for entry through kthe notch 5 and registering throat 14 in the unfastened position of the lock. The` tongue having been entered through the registering parts 14 and 15, and the cap 10 turned to the right by means of the key 18, the parts of the cam 13 of greatestV radii, or farthest removed from its axis of` revolution, first ride over the projection 23 and as the radii of the parts ofthe cam in engagement with the proj ectiongrow shorter, the lid is drawn down with increasing force and is securely fastened down to the body. The cam, extending the greater part of the distance around the cap, departs from its axis of revolution at a comparatively slow degree and is intended to permit a revolution through the greater part of a circle in locking the lid, thereby permitting the more gradual and powerful .drawing of the part 2 to the part 1 with a better locking engagement. The lid having been secured by moving the cap to the'inal locking position, the wire 20 is passed through theregistering holes 6 and 19 and the ends twisted or sealed, thus sealing the lock.

In openingV the lid, the lock is unfastened yby applying the wrench, turning the cap and shearing the wire, due to the action of the edges of the registering holes thereon. While ily applied to any usual structure khaving a lid, door or shutter; that it is readily operated; and that it has peculiar advantages in: Y l

its capacity for drawing and holding parts together, inits adaptability for being sealed and its capacity for shearing the sealing means.

Having described my invention, I claim: 1. A lock comprising a base provided with a circularflangemn combination With a revoluble member having a peripheral part disposed Within said flange, a body, and a cam connecting said body With said peripheral part. 2. A lock comprising a base provided With a circular fiang'e interrupted by a break, a cap provided with a cam and a throat connected to said base so as to' revolve Within said flange, a tongue adapted to pass through said break and throat and to be engaged, by said cam. y

3. A lock comprising a revoluble member having a body bound by a cam and a periphery exterior to said cam, said periphery containing a throat in combination With a fixed member adjacent said member first named, and means for securing said memberstogether to prevent the revolution of said rst member. v

4p. A lock comprising a revoluble member having a body provided withmeans for engagmga Wrench, a cam extending around said body Withincreasing radii through an e angular distance of more than 180 degrees, a

peripheral part containing a Way exterior to said cam, and a tongue adapted to pass ythrough said Way and to be engaged by said cam.

5. A lock comprising a base provided vvith acir'cular ange having a break therein, a cam revolubly connected to said base Within said flange, a member adapted to be engaged by said cam, and means for sealing said cam in locking position to said base.

6. A lock comprising a base containing an aperture, a cam revolubly connected to said base and provided with an aperture adapted to register With said aperture first named, and means comprising a part passing through said apertures for holdingsaid cam in relation to said base. v

7. A lock comprising a base provided with a circular flange and one or more peripheral apertures, arevoluble member having a cam and a peripheral part containing one or more apertures adapted to register with` an aperture or apertures aforesaid, and a Wire extending through registering apertures of said base and member, said base and member being adapted for shearing said vvire.V

In testimony whereof I have hereunto set my name this 17th day of June, 1916.
